An in-depth analysis of the origin of extraordinary sensitivity, fundamental limits, and operating principles of modern biosensors. This electronics course will focus on the physics of biomolecule detection in terms of three elementary concepts: response time, sensitivity, and selectivity. We will use potentiometric, amperometric, and cantilever-based mass sensors to illustrate the application of these concepts to specific sensor technologies.
